The optional ARC and TCS utilize the oil-cooled rear brakes to enhance truck performance and increase productivity. Oil-Cooled Rear Disc Brakes Designed and built for reliable, adjustment-free operation providing superior...

Automatic Retarder Control (ARC) Better machine control, greater production Increased operating efficiency with faster downhill speeds. By maintaining consistently higher engine speeds, average truck speed will be higher than a manually controlled truck. Excellent controllability and reduced operator effort. Automatic brake modulation provides a smoother ride over manual modulation, allowing the operator to focus more on truck operation down the haul road. Improved component life, optimized system cooling capability and reduced torque fluctuations result from ARC’s precision. Faster troubleshooting...

Engine Overspeed Protection With the accelerator depressed and/or ARC turned off, ARC will automatically activate at 2,475 rpm to help avoid potentially destructive and often...

Truck Body Rugged body for varying applications Designed To Handle a Variety of Material Densities. Maximum payload in 3-5 passes with matched Cat loader in material over 1700 kg/m³ (2,900 lb/yd³). Truck Body Features • Sidewall and floor junctions use five-sided beams to resist impact loads and hauling stresses. Box-section beams increase durability in the floor, sidewalls, top rail, corner and cab canopy areas. 400 Brinell Steel wear surfaces provide excellent wear resistance and are easily cold welded. Two-stage hoist cylinders raise in 9.5 seconds, lower in 12.5 seconds. Standard Body comes...

The backbone of the Cat off-highway truck Box-Section Design The 773E frame uses 20 castings in high stress areas with deep penetrating and continuous wrap-around welding. Mild steel provides flexibility, durability and resistance to impact loads even in cold climates. Rollover Protection Structure (ROPS) The ROPS attaches securely to four castings welded into the frame. Frame Features Include: • Integral front bumper and front box beams for suspension cylinder and ROPS support Box-section rear crossmember for body and ROPS support with attachment points for maintenance platform and rear engine...
